Also if I'm right doesn't Dynamite lose rights to Red Sonja at some point soon and then they revert back to Dark Horse and then back to Marvel?
It's been a while since I looked up this topic but IIRC, Red Sonja is owned by a separate company. Something about how when the rights to Robert E. Howard's characters changed hands, the new owners (Paradox?) didn't care to keep Red Sonja because she's a comics character that is only derived from Howard's Red Sonya, so Sonja was pretty much orphaned and a new company formed to get her rights, which were licensed to Dynamite.
That said, I wouldn't be surprised if Marvel tried to get Red Sonja back because she's technically their creation, having debuted on the original Marvel Conan comic, and it would mean that Marvel could reprint more of their own comics without having to worry about gaps involving another licensed character (e.g., they can't currently reprint Red Sonja's appearances in stuff like Marvel Team-Up).
